Engineered to prevent leaks
Braided gland packings — PTFE, graphite, aramid and lubricated grades — that seal rotating and reciprocating shafts in pumps and valves.
Gland packing remains the workhorse seal for valve stems and general-service pumps, and the braid you choose decides how long the gland goes between adjustments. SealGuard packings are densely braided from high-grade yarns with the right lubricant and corner reinforcement for the duty — low-friction PTFE for chemicals, flexible graphite for high-temperature steam, tough aramid for abrasive slurry. The result is controlled leakage, lower stem friction and far fewer trips to the gland follower.

Low-friction chemical-service braidDensely braided PTFE gland packing that seals chemical pumps and valves with low shaft friction and near-universal chemical resistance.
High-temperature fire-safe braidFlexible-graphite and carbon-yarn gland packing for high-temperature steam and valve service, with API 622/589 fire-safe credentials.
Abrasion-resistant slurry braidTough aramid-fibre gland packing engineered to resist extrusion and abrasion in slurry, sand-laden and high-pressure pump service.
Dual-action rotary pump braidPTFE / graphite blended packing that combines low friction with heat dissipation for high-speed rotary pump shafts.
Self-lubricating soft-fibre braidSoft, PTFE-impregnated fibre packing pre-charged with break-in lubricant for clean-water, food and general low-duty pump service.
Field-tested guidance from our engineers on specifying gland packing for demanding service.
Match packing cross-section to the stuffing-box depth and fit a full ring count for even compression.
Choose flexible graphite for high-temperature steam and heat-transfer service where PTFE softens.
Use aramid corners or rings to resist extrusion in abrasive slurry and high-pressure pump duties.
Allow a controlled drip on rotary pumps — over-tightening burns the packing and scores the shaft.
A reliability problem in the field, closed at the joint — and the numbers that followed.
Case StudyAn aggressive acid-transfer service was destroying pump seals roughly every six weeks. Each failure meant an emergency strip-down, lost batch time and a growing reliability backlog across a bank of duty/standby pumps.
We replaced the component seals with balanced cartridge mechanical seals running silicon-carbide faces and PTFE-encapsulated secondary seals, plus a flush plan matched to the duty. The cartridge format removed setting error on rebuild and gave the technicians a repeatable installation.
Mean time between failures moved from six weeks to over twelve months on the lead pumps, and mean time to repair dropped because the cartridge drops straight in. The site redeployed the maintenance hours it used to spend rebuilding seals.
Send us your service conditions — media, temperature, pressure and motion — and our engineers will specify the seal that holds the line.
